# The Jenkins controller: stock Jenkins on Java 25. It runs no builds; the
# client builds run on the agent (docker-compose.agent.yml). On Coolify,
# deploy it as a Docker Compose application from this repository (base
# directory /ci/jenkins) or paste it into a Compose service, with "Connect to
# predefined network" on so the agent can reach it. See ci/jenkins/README.md.
#
# Earlier versions of this file built the controller from ci/jenkins/Dockerfile,
# which is now the agent's image. The service name and data volume are the
# same, so redeploying an existing Jenkins from this file keeps its jobs and
# credentials; its builds then wait for the agent.
